DRIVE GEARING FOR SHAFT SPEED INDICATORS.

Patented Sept. 7, 1915.

APPLICATION FILED DEC. 13. 1913.

said

H, the casing, H, may be so positioned with relation to the shaft, E, as to secure proper meshing of the gear, E, with the idler, G; and incidentally, such adjustment serves to secure upon. the cream separator the entire tram together with the speed indicator itself. Bymeans of this gear train, therefore, it becomes possible to use a stand ard type of speed 'indicatorwithout re-designing its casing to fit in the close quarters afforded-by the desi of the cream separator, and incidental y the speed indicator is more conveniently positionedand is rende'red adjustable to any desired angle to facilitate the observation of its reading.

1. The combination of a rotary shaft, a cylindrical journal bearing therefor, and means for connecting thereto a mechanism to be actuated thereby comprising a gear train, a housing for said gear train having an annular flange dimensioned to encircle the cylindrical journal bearing, and adjustable means carried by the flange adapted to engage the journal bearing for securing the housing thereto.

2. In combination with a rotary shaft, a removable drive crank having a hub formed with clutch. teeth, means for actuating a mechanism by said shaft, comprising a sleeve fixed -on the shaft, circumferentially provided with gear teeth, a gear train meshing therewith for communicating motion to mechanism, said sleeve being also formed with clutch teeth adapted for en gagement with those of the crank hub.

3. In combination with a rotary shaft, a

journal bearing from which it projects at one end, and a driving crank on said end of journal bearing from which it projects at one end, and a driving crank on said end of the shaft, means for actuating from said shaft a mechanism whose casing is wider than the distance between said journal bearing and said crank, comprising a spur gear secured to the shaft between said journal bearing and said crank, a housing for said gear mounted on the journal bearing and extending transversely therefrom, a gear train in said housing terminatin in a shaft parallel to the first-mentioned s aft, and a bushing for said final shaft of the gear train projecting from the extending ortion of said housing for supportin sald" mechanism, the casin of said mec anism havin an aperture to t tightly over said bushing, and means for securing it thereto. p

In testimony whereof witness my hand at Chicago, Illinois, this 10th day. of December, 1913..
